Description:
The AFH1S programmable AC power source provides cost effective
instrument grade AC Power. The unit is designed
to be reconfigured for Three or Single Phase
output, making the AFH1S highly versatile.
The isolated AC output can be controlled
manually using the front panel operator
keypad, or remotely via GPIB/IEEE.448, RS232C
or APG (Analog Programming) for
fully automated computer controlled applications.
All models incorporate PWM technology for efficient power delivery,
and DSP or 16 Bit methodology to provide
precise high-speed measurement of the output.
The AFH1S is provided with a 5" LCD front panel display, built-in
self diagnostics and protection including
Overvoltage, Undervoltage, Overcurrent,
Over Power, Short Circuit, Overtermperature
and Fan Failure.
Each model is provided in a rack type enclosure with caster
wheels and leveling jacks. For added safety,
all input, output and interconnecting cable
connections are contained within the enclosure
behind removable access panels.
